RATCHET FORCE-PUMP.

Specification of Letters Patent.

Patented Jan. 8, 1918.

Application filed December 6, 1916. Serial No. 135,434.

by hand of from a wind-mill, and one object of the invention is to provide novel means for operating the pin which connects the rack bar with the pump plunger, so that, at the will of an operator, the plunger may be operated either from a wind-mill, or by hand.

Another object of the invention is to improve the construction of the rack bar and to improve the construction involving the rack bar and the portion of the plunger which coacts withthe rack bar.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in side elevation, a portion of a pump constructed in accordance with the present invention;

Fig. 2 is an elevation wherein the pump is viewed at right angles to the showing of Fig. 1;

Fig. 3 is a vertical section showing a portion of a pump constructed in accordance with the present invention, parts being broken away;

Fig. 4 is a transverse section showing the details of the pin-shooting device; and

Fig. 5 is a section taken on the line 5-5 of Fig. 1.

In the drawings, the numeral 1 indicates 'a portion of the standard of a pump, the

standard 1 including a head 2 carrying a pivot element 3 on which is mounted a segment or pinion at provided with handle 5. Formed integrally with the head 2 is an upright guide 6 having ears 7 in which is mounted a shaft 8 carrying a wheel 9.

A rack bar 10 reciprocates within the contour of the guide (3, the outer edge of the rack bar being engaged by the wheel t), so that the rack bar may move without undue friction. The rack bar 10 preferably is in the form of an I-member including a body 11 and flanges 12. The rack bar 10 is provided on its rear edge with teeth 1 1 which mesh with the segment or pinion 4. A transverse guide plate 15 connects the flanges 12 of the rack bar adjacent the lower end of the rack bar. The guide plate 15 is provided at one end with an arm 16 terminating in a rectangular-1y disposed finger l7 arranged approximately parallel to the guide plate 15. The rack bar 10 is provided with a lug 18.

The numeral 19 indicates a pump plunger having a head 20 on the opposite sides of which are disposed the lower ends of bars 21 held in place by any suitable means indicated at 39. The bars 21 slide on opposite sides of the body 11 of the rack bar 10 and lie between the flanges 12 of the rack bar. The lower end of a rod 22 is mounted between the upper ends of the bars 21 and is secured thereto in any desired manner as shown at 40. The upper end of the rod 22 is adapted for connection with the driving mechanism of a windmill (not shown) as is common, and-well understood in the art.

A connecting device in the form of a pin 23 is mounted to'reciprocate in openings 25 in the bars 21 of the plunger, in an opening 24 in the body 11 of the rack bar 10, .in an opening 26 in the guide plate 15, and in a similar opening formed in the finger 17. A compression spring 30 is located between the guide plate 15 and the finger 17 and surrounds a portion of the pin 23 One end of the spring 30 abuts against the finger 17, and the other end of the spring is engaged by a suitable abutment 31 carried by the pin 23. The numeral 33 indicates a pitman located along one side of the arm 16. The pitman 33 has a rectangular-[y disposed end 31 through which the end of the pin 23 passes.

A securing device is mounted in the end of the pin 23, the end 34L of the pitman 33 lylng between the securing device and the finger l7. The pitman 33 is pivoted at 35 to a lever 36which is fulcrumed at 37 on the arm,

16. The lever 36 is provided with an extension 38, the extension 38 and the pivotal 0011- nection 35 between the lever and the pitman.

34' lying on opposite sides of the i'ulcrum 37 of the lever.

When it is desired to reciprocate the pump plunger l92l-22 by hand, through the medium of the handle 5 and the segment or pinion 4, then the lever 36 is swung into.

The,

a reciprocation may be imparted to the pump plunger by means of the handle 5 of the segment oi pinion t.

lVhen it is desired to operate the pump plunger from a wind mill, then the lever 36' is swung downwardly from the position of Fig. 2, until the extension 38 ot' the lever engages the lug 18. By this operation, the

pitman 33 is moved backwardly, and the end.

3e of the pitman, cooperating with the pin 23, will retract the pin 23 until the pin is free of the bars 21 of the pump plunger. The pump plunger cannow reciprocate with respect to the rack bar 10. Because the lug 18 is located above the fulcrum 37 otthe lever 36, the extension 38 ot' the lever will remain engaged with the lug 18 when the spring 30 is compressed by the rearward movement of the pin 23 under the actionof' the pitman 33.

In devices of this type, if the pin 23 is loose, it is likely to be lost, or it held in place temporarily by a chain or cord, the pin, at best, when retracted, is not in such a position that it can be used readily to connect the pump plunger and the rack bar. In the present invention, the pin 23 is always in place, and may be manipulated readily by a simple mechanism comprising the lever 34 and the pitman 33. v

The plunger, comprising the parts 21' cooperates in a novel manner with the rack-bar 10 which is in the form of an I-bar and.

avoids known objectionable constructions in which the pump plunger slides inside of the.

rack j bar.

Copies of this pat entrmay be obtained for five cents each, by addressing the Commissioner of Patents,

Having thus described the invention, what is claimed is l.- In a combined hand and wind mill pump,- a supporting structure including a guide; a racK bar slidable in the guide and.

in. the form of an I-member including a body and flanges; a pump plunger including spaced bars slidable between the flanges of the I-member and located on opposite sides of the body'thereof; a detachable connection uniting one of the spaced bars of the plunger with the rack bar; and a segment mounted to swing. on the supporting strucs ture and meshing into the ram: bar.

2. In a combined hand and windmill pump, an operating member andoa, pump plunger having relative'right-line movement with respect to each other, the operating member being provided with an arm terminating in an angular finger; a pin slidably mounted in the linger and in the operating member 'andconst1tuting a detachable connection between the operating member and the plunger; a compression spring engaging the linger; an abutment on the pin engaging thespring; .a leverfulcrumed on the operating..men1ber; and'a pitman forming an operative connection between the lever and .the pin, andconstituting means for retracting the pin against the action of the spring.

In a combined hand and wind mill pump, an operating member and a pump plunger having relative right-line movement with respect to each other, the operating member being provided with an arm having an angular finger; a pin slidably mounted in the finger and .infthe operating. member and forming a detachable connection between the operating. member and the plunger; a

spring abuttingagainst the finger; an abutment on the pin and engaging the spring;

a lever fulcrumed intermediate its ends-on the operating member; a pitman forming a connection between the lever and; the pin;

anda lug on theoperating. member wherewith one end ofthe lever engages when theleveris swung onits fulcrum t-o putthe spring under compression andto elfect a retracting of the pm.

In testimony that I'cla'nn the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
